Forces the PPG to redraw itself. This is useful if the PPGLayout is changed within logic code, or a Parameter is hidden with Parameter.Show. However Softimage automatically refreshes the UI when the value of a Parameter changes.
This method should not be confused with XSIUtils.Reload which re-executes the DefineLayout callback (or reloads the SPDL file) before doing a Refresh of the user interface.
